某汽车尾箱支架零件形状结构复杂,包含冲孔、压筋、翻边、弯曲等冲压工艺特征。对该零件的冲压工艺性分析表明,采用级进冲压工艺方案能很好地满足所需尺寸精度及大批量生产需求;根据零件的冲压工艺特点及对排样的排列方式、载体形式和冲制顺序的分析,得到单排、斜排、中间载体的18工位排样图;根据排样图设计和选用凸、凹模结构及模具辅助零件,如斜刃口冲裁凸模、弹簧柱塞式的防止废料上浮装置等,最终完成了模具的总装配。试冲结果表明,所设计的18工位级进模结构合理可靠,产品成形质量好、生产效率高,可以满足大批量生产的需要。
A car trunk bracket parts shape and complexity of the structure, including punching, pressing, flanging, bending and other stamping process characteristics. The stamping process of the part analysis shows that the use of progressive stamping process scheme can well meet the required dimensional accuracy and mass production requirements; according to part of the stamping process characteristics and arrangement of the arrangement of the carrier forms and punches According to the layout drawing design and selection of convex, concave die structure and mold auxiliary parts, such as bevel edge punching punch, spring plunger Type of anti-scrap float devices, and ultimately completed the assembly of the mold. The test results show that the design of the 18-position progressive die structure is reasonable and reliable, good forming quality, high production efficiency, to meet the needs of mass production.
